My area of research is around neonatal immune system development and the role of infection/inflammation in maternal and child health. The research programs are summarized below:
Biological mechanisms for clinical effects of Zn supplementation in infants less than 2 months of age with severe infection (funded by SERB). [This study is embedded in a zinc supplementation trial funded by the Research Council of Norway, Centre for Intervention Sciences in Maternal & Child Health, Norway.]
Zinc supplementation is known to be effective in treatment/management of diarrhoea and sepsis, but has shown mixed results for acute lower respiratory tract infections. It is still not clear if the effect of zinc is through correction of Zn deficiency or direct immunomodulation and whether the effects differ depending on the etiology of infection (broadly, viral vs. bacterial). To address this problem, we have been looking at the immune cell signatures, and intracellular Zn levels at enrolment and post zinc supplementation in a subset of patients enrolled in the trial, to correlate these signatures with clinical outcomes. Moreover, as a large number of neonates with sepsis turn out to be culture negative, high throughput sequencing will be used to look at the etiology of sepsis and correlate the same with success of zinc supplementation. Whole blood gene expression studies will help distinguish bacterial and viral etiologies depending on the host gene expression pattern. The gene expression profiles at enrolment will also be used to diagnose and predict the outcome of sepsis.
Effect of infections and inflammation during pregnancy on adverse pregnancy outcomes, specifically preterm birth (PTB) and fetal growth restriction (FGR)
In an ongoing cohort, pregnant women are being followed up from early first trimester till delivery for risk stratification of PTB. By generating multidimensional clinical and biological data we are identifying temporal associations between the maternal inflammatory status in pregnancy to PTB and FGR. Data on reported infections during pregnancy is being recorded and we will be measuring markers of inflammation across all 3 trimesters in a normal pregnancy and also in those that lead to FGR and PTB to use a subset of serum cytokines as biomarkers to predict the risk of PTB and FGR.
